Abstract:The reproductive growth index and model,e.g leaf area,leaves/ear,dry weight,grain weight,1000-grain weight,full seed percentage of 9000kg/ha yield of three early varieties (Changbai7,Tong 24-1 and Tongxi 112)with types of spike number,ear weight and passage form of rice at five cultivation patterns(30.0 cm × 13.3 cm,30.0 × 20.0 cm,30.0 cm × 26.6 cm,40.0 cm × 20.0 cm,50.0 cm + 30.0 cm × 20.0 cm)in reproductive growth period (from july,30 to september,15)have been reported.And the character difference of reproductive growth period and yield components and composition of rice colony in five cultivation patterns are also summarized in this article.
